Answer:
976.80
Step-by-step explanation:
880 times 0.11 to find amount that it increased by added to the amount it was gives you 976.80
Let x= the usual speed
1500/x would equal how long it usually took the plane to read the destination
1500/(x+100) would equal how long it would take the plane now
So
because it would lose 30 minutes already
Simplify:
The usual speed was 500 hm/hr
The regression equation given to us is y = 0.5x + 1.3
It is in the form y = mx+b
m = 0.5 is the slope
b = 1.3 is the y intercept
The slope of 0.5 indicates that each time x increases by 1, the value of y will increase by 0.5 (since 0.5 = 0.5/1)
Translate this into the context of the problem and that means "for every extra person attending (x), the prep time increases by roughly 0.5 hours" which is what choice C is saying, well a paraphrase of it anyway.
Answer: Choice C
Answer:
Step-by-step explanation:
Notice that we can factor the expression as . Similarly, we can express as . Now, we can multiply the fraction together as .
Jack left 16.66% of gratuity for the waiter.
Step-by-step explanation:
Given:
Restaurant bill amount = 52.00
Total bill jack paid = 62.40
To find:
percent of gratuity Jack left for the waiter = ?

Lets first find the amount jack gave has gratuity to the waiter
The amount given for gratuity = 62.40 - 52.00
The amount given for gratuity = 10.40
Now the percentage is
=
=
= 16.66 %
